Also `s/coinJoinEnabledChanged/showCoinJoinChanged/g` to establish a
naming convention that will be used soon.

This should fix the misalignment of the `subFeeFromAmount` `QCheckBox`
compared to the rest of the `QCheckBox`es

Inheriting the whole structure is overkill just to use `tr` and `hash()`
is used in hot loops so we should cache the value in the ctor.

Also remove dead variable.

This is closer to how we report details for transactions and more
translation-friendly and easier to copy.

Visiting URLs could be dangerous, add a warning before we open a link in
someone's browser.

Dash Governance Tools' budget generator is a much more visually friendly
design and we can model our wizard after it.

The visual language should match other coin-spending activities, also
warn that that you don't get the fee back.

The proposal creation process can be interrupted for reasons beyond our
control, since submitting the actual proposal is different from spending
the collateral, it should have its own page.

Right now this removes the old code but doesn't create a new layout, we
will do that in the next commit.

This replaces the remaining pages of the proposal wizard that we removed
in the last commit.

You cannot create a proposal without an adequate balance, it's a bad
idea to allow any kind of proposal manipulation without being synced.

This is a more inexpensive operation since we aren't getting a diff set,
we're getting the whole list repeatedly.

We are no longer using the wizard format so the name is a misnomer, the
logic is also relatively simplified (as now half of it is in
`qt/proposalresume.{cpp,h}`)

Applying our font causes drift to be introduced for some reason if baked
into the layout but this doesn't seem to be an issue if done
programmatically
